Matt, your sword is an army contract sword made by the Seven Lives Sword Forging Dōjō. If you look carefully, usually between the characters 生 and 刀, you will find a faint "star" stamp or a 阪 final inspection mark. One or the other marking has been reported on all Type 100s made so far by this dōjō. To date, only these Type 100s have been reported to have a serial number on the nakago mune. Besides the army contract, this dōjō undertook custom work. For example, see the Masanaga 正永 swords depicted at the links below. Minatogawa 1945 MINATOGAWA SHRINE SWORDS The oldest reference I have run across so far is the description over at RiceCracker.com. Katana - Masanaga (Ito Masakiyo)

七生刀鍛錬道場 Shichishō Katana Tanrendōjō By Nick Komiya 刀 [katana] is a prefix for 鍛錬 [tanren]. So it is read シチショウ　カタナ　タンレンドウジョウ (Shichishō Katana Tanrendōjō). 道場 [dōjō] is a place where you practice and learn all forms of ドウ [dō], not only martial arts, but also calligraphy (ショドウ shodō), flower arrangement (カドウ kadō) or tea ceremony (サドウ sadō) are all categorized as an art form of ドウ [dō]. ドウジョウ [dōjō] can also be a training course that is very intensive, used like 日本語道場 [Nihongo dōjō]. In this case of 刀鍛錬道場, the ドウジョウ (dōjō) is being described as a place or training course to practice タンレンドウ (tanrendō).

I asked Nick Komiya whether the character 刀 is a suffix of 七生-刀 or if it is a prefix for 刀-鍛錬. In addition, I was confused by the use of the term dōjō 道場 which I associate with a place for martial arts training and not sword production. Nick's reply can be seen in the post below. I have added the rōmaji pronunciation for the kanji in brackets and the kana characters in parentheses so as to avoid others having to look it up. I realize it is a bit unsightly and detracts from the flow; but, it gets the job done.

Ed, the tang reads 山川秀夫 Yamakawa Hideo and it has been seen before. Tang Inscription Translation

Nick just started a thread on the 12th about this subject matter. A little technical but worthy of a look. The “B&W in Color” Fallacy

Since posting, I ran across this 2008 post by @hemi-man that can be seen above after editing. The reference to shichisei is just another way of saying shichishō 七生.

@k morita I sent you a private message in Japanese 日本語 about this topic.

Hi Matt, I have not looked into these nor made a file folder for them. It does seem they are serialized on the nakago mune. See the Masanaga 正永, serial 21, at the link below. 北武备-三式七生 正永（极特殊） @BANGBANGSAN Does the Chinese text have anything to say about 七生刀鍛錬道場? These swords seems to have some sort of association with Kusunoki Masashige 楠木正成 and the Minatogawa Shrine 湊川神社. There is a monograph on the Minatogawa Shrine swords; alas, I do not own a copy. Maybe someone reading this will have a copy and can take a look to see if 七生刀鍛錬道場 is mentioned or not. Wallinga, Herman A. Gendaito Made at the Minatogawa Shrine. 2000. [35 pages.] 七生 = Shichishō = 7 lives [possibly related to 七生報國 by Kusunoki Masashige] @SteveM is that the right rōmaji ローマ字?

Thanks for the prompt reply Chris. I asked as I could not find the small screw 小ねじ that holds the koiguchi 鯉口 on. In hand, is the scabbard color red or burgundy? It is hard to tell from the pictures. FYI, the late Barnes san recorded 名83725. This is one digit higher than the one you depict above!

It is a Type 95 Military Sword that was used by the lower ranks. @Shamsy or @Stegel will need to look at the scabbard color to determine if it is kosher or not. Do you have a picture of the scabbard mouth showing the serial number? Below is a little primer for your friend to get him started on what he has. IJA Type 95 NCO Sword Info

七生刀鍛錬道場. Matt, I have run into this marking before on a Masakatsu 正勝. Katana [Nakamura Masakatsu] Edit: I remember now that the Masakatsu had Arabic numbers stamped on the nakago mune. Another Masakatsu had a faint 阪 final inspection mark on it. Does your 正永 have a number stamped on the nakago mune or a 阪 inspection mark?

I asked Nick Komiya over at WRF to take a look at this and above is his reply.

Cheers mate!

David S., after March 1945, anything is possible in regards to Japanese swords. Starting in the last year of the war, all kinds of patriotic sword production took place. Type 98 sword with unusual mark on tang Wartime Japanese Radio Broadcasts Related To Swords

The wrong order of characters my friend. In this case, 觀耕台 means "viewing platform" while I think the characters would more likely be in the order of 耕觀? Me thinks Trystan has been imbibing on 烧酒 shāojiǔ!

The top row is PHOTO and the second row appears to be a sequence of numbers. I think the photograph is probably coming from an archive, news agency, or collection. Scrap the studio and date comment above. This just goes to show you what happens when I think drink too much!

Yes, C96 to be exact and commonly called the "broomhandle" by collectors. The Japanese acquired so many from the Chinese that they adopted it as the ｢モ｣式大型拳銃 in 1939! Good to see Mal branching out into the heavy artillery! Mauser C96

Ditto what Shamsy said. Note the name of the photographic studio and date in the lower left corner?

Here are the characters for Nagayama Kōkan 永山･光幹 courtesy of the NDL. Unlikely this inscription is referring to him.

Chris, wrong Shigemitsu 重光. We pay you waaaay to much money for these kind of mistakes! I would suggest doing a search on NMB for Shigemitsu, paying close attention for the mei 繁光. There are two spellings that you will run into as indicated below. Shigemitsu -- 繁光 Shigemitsu -- 重光

Several Sukehisa 祐久 are archived on NMB and some are in naval mounts. Two of them have a unique white painted subassembly number. Me thinks Mal will need to revise Japanese Naval Swords, Part 2! Translation of Katana Mei Need help identifying mei of 2 Shin Gunto please! Kai-Gunto Translation Help Katsuhisa?

The sword is depicted in F&G and in Dawson's books. Both state it is for the Imperial Household. Ministry of the Imperial Household

Yes, 1943 is the date. The first character is alluding me at the moment so I will have Mal take a look at it. Can you post an overall picture of the fittings? @mecox

At long last, I tracked this down to an actual source via a Russian webpage. It is not coming from a book but rather a series of articles. I have been able to reconstruct the citation for part 2 of the article or series? Okōchi Tsunehira 大河内･常平.
